Would anyone have the wiring diagram for the 1920’s PA truck?  Trying to trace out the starter motor circuit.

Hopefully 1927 isn’t too far removed…

Does this help you any?

Ron,

In Pierce-Arrow cars of this era, the ( – ) cable went directly to the starter (as shown in the diagram Carl posted) and there was an internal switch mechanism inside the starter housing.  It was activated by a mechanical linkage from a foot pedal. Later 20’s cars (with dual valve engines) had a slightly different mechanism, but still internal. I do not know if the trucks were the same as the cars.  Below is a diagram of the early 20’s X Series truck starter. Hopefully this will be of some use to you.  You might check with Karl Krouch as he is familiar with the trucks.
